Use of 2-Hydroxy-4-Isobutoxy Acetophenone Oxime as Spectrophotometric Reagent for Copper

Authors(1) :-Dr. J. R. Shukla

2-Hydroxy-4-isobutoxy acetophenone oxime(HIBAO) has been used for the spectrophotometric determination for Cu(II) at pH range 7 to 9 in chloroform medium. Job’s method for continuous variation, Yoe and Jones’ mole ratio method, the slope ratio method show metal ligand ratio in complex to be 1:2. The stability constant of the complex is found to be 4.32 X108. The dark green coloured complex obeys Beer’s law in the concentration range 31.77 to 444.78 ppm for Cu(II) ion, while the optimum concentration range from Ringbom plot is found to be 127.08 to 381.24ppm. The photometric sensitivity and molar absorptivity at the 650nm are found to be 0.488µg/cm2 and 130 l mol-1cm-1 respectively. The standard free energy of formation of complex is -12.00 kcal/mole at 30oC. The complex is stable for 48 hrs. The reagent has also been found to give quite satisfactory results for Cu(II) present in alloy like brass, bronze and synthetic mixtures. The antimicrobial Activity of HIBAO and Cu-HIBAO complex have also been checked.
